There are several reasons why a speaker has volume issues. It could be because of the speaker's battery, the device connected with the speaker, the audio source, and so on.

If your Soundcore Boost's volume is too low, please try these steps:

• Confirm that Soundcore Boost is fully charged
• Reset Soundcore Boost by holding the Power button for 4 seconds 
• Connect Soundcore Boost with another device
• Try a different app or audio source
• Make sure to turn up the volume of both Soundcore Boost and the paired device

If the volume issue persists, please contact us at service@soundcore.com for further assistance. Make sure to mention that you have tried the listed steps so our agents do not ask you to repeat them.
